I don't know. I think that we're supposed to feel the anguish of forbidden love, and not whiny gnocchi making.

Seriously, though, I think it is supposed to be anguish for the two of them. Vincent promises that he will not go near her any longer, and she doesn't understand his rebuff. Although I think that Andy Garcia does a commendable job with his sad eyes, I think that Sophia, rather than playing that scene like an innocent young girl who doesn't understand his rejection, plays it like a whiny brat who has been denied a new pair of Manolo's.
